Flicker free ON/OFF
Flicker free can be switched off to bypass the digital frame
store and have the video assist output with no delay.
The typical running speed for the lm camera is different to
that of the video assist. e.g. the lm camera runs at 24 fps
and the video assist at 25 fps for PAL or 30 fps for NTSC.
Without icker processing this speed difference causes
varying brightness between successive individual video
images. To eliminate this so called icker, video images are
stored at the speed of the lm camera into the video frame
storage and recalled in the speed of the video system. This
storage might cause a slight delay, which is not desirable
in some time-crucial conditions, e.g. motion control or
shooting of a pop video. Therefore it is possible to switch
the icker free system off. This will eliminate the delay.
However, icker will occur in this mode.
In parallel to the control via keypad, the icker free off can
also be programmed via the on-screen menu.
Move the cursor > with the keys Ê and Ë to the line
– FLICKERFREE. Pressing the key Í or Ì will switch
icker free mode off and on.
